12:49 AM _unreal_: ve7it, hehe shipped march-apr.
12:57 AM _unreal_: other link likely :)
01:14 AM Deejay: moin
01:17 AM flyback: https://www.youtube.com/watch?v=DLz6pgvsZ_I
01:20 AM Loetmichel: mornin'
02:32 AM X704 is now known as tiwake
02:36 AM Loetmichel: *giggle* i really like that MoI 3d "cad"... coworker just came with the shards of a drive gear for a meat grinder... took 20 minutes then it was designed and sliced and the 3d-printer is heating up. If it fails again i will just mill it out of alu on the CNC router ;)
02:54 AM Loetmichel: http://www.cyrom.org/palbum/main.php?g2_itemId=17666&g2_imageViewsIndex=1 <- diameter 22mm... that HAS to break because of so little material left between the chamfer for the screw and the square drive... :-(
03:27 AM Loetmichel: *MUHAHAHA* i really have to much power. just left the workshop, pressed/turned the door handle a BIT to late. The 8mm brass bolt that locks the other half of the door in the floor sheared off clean. Thats a way to open a door, too ;)
03:28 AM X704 is now known as tiwake
03:44 AM rtce9a: hi, Im setting up my stepconf when trying to test my axis with that run icon the stepper does not work, but after i create the config im able to move the axis, can some one tell me why i cannot test axis during step conf wizard ?

04:55 AM Tom_L: morning
04:57 AM XXCoder: hey
05:03 AM XXCoder: ohh this one looks interesting https://www.youtube.com/watch?v=u71kzF1XfQM
05:03 AM XXCoder: lathe restoration
05:03 AM XXCoder: rather old one
05:09 AM XXCoder: 1886.
05:28 AM XXCoder: glad they didnt excessively file or use bondo
05:28 AM XXCoder: ot both
05:30 AM XXCoder: theres spoof video where guy restores old large nail like those dumb restoration guys (not guy in video I linked to)
05:30 AM XXCoder: nail had full works, debending, strip, de-rust, filing, bondo and paint to look better
05:36 AM jthornton: morning
05:36 AM XXCoder: hey jt
05:36 AM XXCoder: if you got plenty data check out that vide
05:36 AM jthornton: free time till 8am
05:37 AM XXCoder: hes restoring 1886 lathe. and hes not "in your face" well except for into anyway
05:37 AM XXCoder: *intro
05:37 AM XXCoder: hes closer to professional restorer so no bondo and really shitty welds
06:15 AM jymmmm: This is awesome... https://www.youtube.com/watch?v=1YbN-ssuOQo
06:56 AM X704 is now known as tiwake
07:01 AM X704 is now known as tiwake
07:07 AM Loetmichel: uups... my workdesk notebook just went to sleep. thats not supposed to do that unless battery operated... *sniff* "it smells like burned plastic here"... crawling under the desk: the car plug of the generic 12V->19V PSU for said notebook looks like a colani edition... completely molten... seems it wasnt the best idea to just wind a bit of wire around the contacts of said plug to supply it
07:07 AM Loetmichel: from a 12V 10A meanwell ;)
07:08 AM XXCoder: the day in work adventures life
07:11 AM Loetmichel: more like: the things we do to botch the tools into working... :-)
07:11 AM Loetmichel: no idea where the original power brick went
07:11 AM XXCoder: :)
07:11 AM XXCoder: talking about power bricks
07:11 AM XXCoder: I bought one for mini belt sander
07:11 AM XXCoder: it literally disappeared after that test. I still cant find it anywhere. :(
07:12 AM XXCoder: i had huge misadventure at work today too. I was blamed on pins being rusty due to cleaning agent left in pins box
07:12 AM Loetmichel: that said: i distinclty remember to have had that notebook in the car... gimme a moment!
07:12 AM XXCoder: I had to de-rust all of em. took me hours
07:13 AM XXCoder: 0.06" to .500 is a LOT of pins lol (.001" increments)
07:19 AM Loetmichel: after some archeology^W digging: nope, not in the car. must have been the old BMW convertible... but i fond another notebook that i missed for a while now... also without PSu ;)
07:19 AM XXCoder: lol
07:21 AM Loetmichel: car has a bit of "geolocical layers" going on in the trunk/back seats
07:21 AM XXCoder: heh I ban such thing
07:21 AM Loetmichel: the deeper you get the older the tools/trash are ;)
07:21 AM XXCoder: i never had a messy car
07:21 AM XXCoder: thunk have some backup stuff
07:21 AM Loetmichel: <- always drives old beaters
07:21 AM XXCoder: some very specific to me
07:22 AM XXCoder: well I always did too till I got 2012 ford lol

12:26 PM unterhaus: andypugh, I can't get anything to load those stl files on your github. Is it possible stl files have newline problems?
12:41 PM skunkworks: unterhaus: what stl files?
12:42 PM unterhaus: for the fan clip and the spacer
12:42 PM unterhaus: on the stumbl
12:43 PM unterhaus: I'm cloning his github to see if that helps
12:46 PM unterhaus: that did help, save file as did something to it
12:47 PM skunkworks: unterhaus: yah - it opens just fine in cura downloading it from his git
12:48 PM skunkworks: heh - I didn't know github had an stl viewer/
12:52 PM unterhaus: huh, it opens it as text on my comp
12:53 PM unterhaus: skunkworks, I assume you are using linux?
12:53 PM skunkworks: yers
12:53 PM skunkworks: ?
12:53 PM skunkworks: yes
12:54 PM unterhaus: I feel like Bill Gates did something to the files when I d/l them
12:54 PM skunkworks: can't you open them directly in your favorite slicer/cad program?
12:55 PM unterhaus: temporarily cad-deficient
12:55 PM unterhaus: no 3d printer, I'm getting someone else to print them for me
12:56 PM unterhaus: github displays the files for me, not sure what happened previously
01:02 PM unterhaus: the only openscad file that opens and shows anything is the spacer
01:02 PM unterhaus: other ones have some code to the side. Is there a run button I'm missing?
01:14 PM unterhaus: I thought about getting shapeways to print them, $8 apiece
01:15 PM unterhaus: searching google for openscad doesn't yield any results on why nothing is displayed when I open the stmbl files
02:19 PM gregcnc: yey! mill is finally back together. I ended up taking the motor apart yet again and rebalancing it.
02:19 PM unterhaus: congrats
02:20 PM gregcnc: I should have just done this at the first sine of trouble
02:20 PM gregcnc: sine lol
02:21 PM gregcnc: my fingers do whatever they want
02:28 PM Rab: unterhaus, tried Design -> Preview [F5] in OpenSCAD?
02:38 PM unterhaus: thanks, that doesn't do much
02:39 PM unterhaus: geometries in cache 0 isn't real promising
02:42 PM unterhaus: only files that display are stmbl and spacer
02:43 PM unterhaus: I'm wondering if it's a path issue
02:44 PM unterhaus: but there are no errors on compile
02:50 PM Rab: FWIW those are the only two files that preview for me. But I know nothing about OpenSCAD.
02:54 PM Rab: Well, I got v4_bracket.scad to preview by uncommenting //bracket2();
02:57 PM unterhaus: there you go
02:59 PM unterhaus: added a clip(); to the end of clip and it ran. starting to see a pattern here
03:01 PM unterhaus: I'm a bit curious why this is
03:02 PM Rab: I guess they're only intended/tested as resources for stmbl.scad, which pulls in pcb_simple.scad, v4_bracket.scad, and clip.scad.
03:03 PM unterhaus: okay, that makes sense
03:04 PM unterhaus: I guess you can expect a few weird things out of OSS
03:04 PM unterhaus: the fan clip scad seems to be missing
03:04 PM Rab: Probably wise to get a reply from andypugh before committing those files to Shapeways.
03:06 PM Rab: STMBLFanClipsv1.stl?
03:06 PM unterhaus: no scad file though
03:06 PM unterhaus: I am getting someone local to print them, just using shapeways to check the files
03:06 PM unterhaus: they are pickier than most
03:07 PM unterhaus: I was thinking about treeing up the parts so they would cost a reasonable amount
03:08 PM unterhaus: you have to put the parts in a store before they become public
03:09 PM unterhaus: I did get the stl files to work okay
03:13 PM CaptHindsight: thermoplastic STMBLE enclosures?
03:19 PM unterhaus: I recall seeing that someone printed a stmbl encloser
03:20 PM unterhaus: I'm just getting the irams spacers and fan clip printed. And Andy says I'll probably melt the IRAMs spacers
03:22 PM unterhaus: I am probably going to get the enclosure laser cut
03:45 PM unterhaus: I kinda wonder if it would be less expensive if it wasn't one piece
04:04 PM Deejay: gn8
04:46 PM _unreal_: ve7it, well this weekend I think I'm just going to go with typical resistors for the few that I'm missing. I have not gotten around to ordering them from digikey etc... and only a few are needed. would rather go with the SMD's but I dont have them on hand. :/
04:46 PM _unreal_: The caps I do believe I have all of the SMD caps on hand
04:47 PM _unreal_: also planning on getting the pics programmed this weekend. I want to see if I can get the motors spinning this weekend
04:47 PM _unreal_: saddly I have a number of house projects I have to work on as well
04:47 PM _unreal_: like finishing cleaning the pool
04:48 PM perry_j1987: hmm will a machine vise hold several chunks of metal tightly to machine all the same features at once? :P
04:48 PM _unreal_: perry_j1987, IF they are all the same size
04:48 PM _unreal_: but I would NOT suggest it
04:48 PM perry_j1987: was contemplating use c clamp to squeeze them in other direction together maybe
04:48 PM _unreal_: perry_j1987, typically two is the max. one on one side of the clamp and one on the other side
04:48 PM _unreal_: I wouldnt
04:49 PM _unreal_: all it takes is one to slip
04:49 PM perry_j1987: aye
04:49 PM perry_j1987: i need to make pallets
04:49 PM _unreal_: pallets?
04:49 PM perry_j1987: plate that will hold them with toe clamps on each piece
04:49 PM XXCoder: perry can machine all blocks to same width
04:49 PM perry_j1987: fixture
04:50 PM XXCoder: then can clamp them in multiples
04:50 PM _unreal_: perry_j1987, unless they are IDENTICAL dont gang them.
04:53 PM XXCoder: at work some tiny parts we use 2 per jaw
04:53 PM XXCoder: left and right edges
04:53 PM XXCoder: tend to be fine. theres rare part fly off but its often still usable
04:54 PM XXCoder: note all blocks is same from extrusion and cut to pretty much same size
04:56 PM XXCoder: also, very light cuts. skim surface, add key and locating bores
04:56 PM XXCoder: so we can put em on pallet with techi-grip
04:56 PM _unreal_: XXCoder, my machine is getting closer
04:56 PM XXCoder: nice
04:56 PM XXCoder: whats left to do?
04:56 PM _unreal_: when I get around to it I'll post latest photos
04:56 PM _unreal_: Z is not even touched
04:56 PM _unreal_: Y is more or less done
04:57 PM _unreal_: still need to setup the motor and pulley.. X I need to build the lead screw drive system
04:57 PM XXCoder: :)
04:57 PM _unreal_: the liner bearings are "" finished ""
04:57 PM _unreal_: i'm not happy with them. I have a .5mm dip in an area
04:57 PM _unreal_: I think its the extrusion of all things
04:58 PM _unreal_: I'd hate to but if I keep having alignment issues I may switch to Steel for the mounts :(
04:58 PM _unreal_: steel aangle iron
04:58 PM XXCoder: .5mm? wonder if you can mill extrusion for flatness
04:59 PM _unreal_: it would be the ends then
04:59 PM XXCoder: mount it in jaws, indicate it for flatness then mill
04:59 PM _unreal_: and I'd be milling the area that the T nuts use to secure to
04:59 PM _unreal_: so I'd tend to think ill of doing that
04:59 PM XXCoder: cool
04:59 PM _unreal_: I dont have a milling machine :(
04:59 PM XXCoder: drat oh well
04:59 PM _unreal_: wish I did
05:00 PM _unreal_: I could stack some paper
05:00 PM _unreal_: but I dont think I want to deal with that BS as well :(
05:00 PM XXCoder: orobably can do grinding but you would need to somehow ensure that table is at exact 90 degree heh
05:00 PM XXCoder: nah get good steel shims
05:00 PM XXCoder: its always in range of sizes
05:01 PM _unreal_: still wondering if I should have just gone with buying a few chunks of the same extruion that I used on the lower area. for the X
05:01 PM _unreal_: would be overkill
05:02 PM _unreal_: I lost count of how many people said I should mount my X vertical
05:02 PM _unreal_: now I'm kind of wondering if I should have hehe
05:02 PM _unreal_: not that I couldnt still
05:03 PM XXCoder: yeah
05:03 PM _unreal_: I like my deign better though
05:03 PM _unreal_: sigh
05:04 PM _unreal_: So my father is home finally from his hospital stay
05:04 PM _unreal_: have not even set eyes on him yet
05:04 PM XXCoder: why not?
05:05 PM _unreal_: lucky?
05:05 PM perry_j1987: XXCoder when your doing a block on each end of the vise do you use some sort of vise stop between them or from the outside somehow
05:05 PM XXCoder: nah we just used jaw edge as reference. part is bit smaller than block so small errors there dont matter at all
05:05 PM _unreal_: perry_j1987, when your clamping with a vise the idea is to use each end
05:06 PM _unreal_: because the vice will flex, so if each end has a same sized block, then they should be find
05:06 PM perry_j1987: i've just been doing one at a time so far
05:06 PM _unreal_: as I said one is fine two is typacally the limit
05:06 PM _unreal_: especially for HEAVY cutting
05:08 PM _unreal_: just shelled out $80 last night on two caps
05:09 PM _unreal_: 27,000uf 75Vdc
05:09 PM _unreal_: off ebay
05:09 PM XXCoder: fancy heh
05:09 PM _unreal_: This is my bible https://www.powertronix.com/userfiles/kcfinder/images/Linear-Power-Supplies-4.jpg
05:09 PM _unreal_: err build design
05:14 PM XXCoder: cool :)
05:15 PM _unreal_: XXCoder, I have an other version of the same schematic that has resistors in parallel with the caps
05:16 PM _unreal_: any idea what value would likely be used? the voltage should be 24vdc
05:16 PM XXCoder: heh i dont know much about electrics design :)
05:16 PM _unreal_: ya dead to me
05:16 PM _unreal_: :)
05:16 PM XXCoder: lol
05:16 PM _unreal_: I'm guessing 1meg resistors
05:17 PM _unreal_: something that will help draw down the caps to zero when off
06:00 PM JT-Shop: I use indicator lamps
06:17 PM _unreal_: There just soldered two of the "ONLY ONES I have on hand" opamps onto my driver boards.
07:27 PM daveland: anyone use pluto-p recently ?
07:29 PM daveland: halcmd: loadrt pluto_step
